Question

If we are running a hypothesis test to see if the true mean breaking strength of Acme rope exceeds 1000 pounds at significance level .025 with a sample of size 4 and we assume that Acme rope breaking strength is normally distributed with standard deviation 50 pounds, then what is the critical value of the standardized test statistic (three decimal place accuracy) for this hypothesis test?

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
